摘要: 该文采用基于动态嵌套网格技术上的双时间法,模拟了飞行器导弹发射时的粘性流场和导弹气动性能的变化,湍流模型为K-ω两方程模型.该文研究的是一个简单的二维模型,但所得的结论有助于理解和掌握激波对飞行器发射导弹的飞行速度、飞行稳定性和飞行轨迹的影响,并具有一定的参考价值.

关键词: K-ω湍流模型, 动态嵌套网格, 双时间法

Abstract: This paper simulates the process of an airlaunched missile traversing across a shockwave, using a dualtime method based on a motive chimera grids and the K-ω turbulent model. By studying a simple 2D model, the results provide useful reference for understanding interference between the moving missile and the shockware, which may directly affect the velocity and trajectory of the missile.

Key words: dual-time method, K-ω turbulent model, moving chimera grids, shockwave, missile launch
